Prompted for Admin rights when trying to run NAV

We are running Microsoft Business Solutions 3.70, Ceres 2.5 IE NAV 4.0 SP3 on Windows 7 64bit machines. No problems with any machines but one. Machine appears to be setup identical to the rest but even when NAV client is run under an admin login it is requesting admin rights to run then errors.

Welcome to DUG!!!

Can you paste exact error message hereā€¦ ??

I completely turned off UAC, uninstalled the entire program, restarted, reinstalled, restarted and still get the same message.
